- Irritant / corrosive response data:
- After a 3-minute exposure: No cutaneous reactions were observed at the 1-hour reading. A severe erythema (grade 4) and a severe oedema (grade 4), together with cutaneous necrosis, were noted on days 2 and 3.
After a 4-hour exposure: A well-defined erythema (grade 2) and a slight oedema (grade 2) were noted at the 1-hour reading. A
severe erythema (grade 4) and a severe oedema (grade 4), together with cutaneous necrosis, were observed on days 2 and 3. - Other effects:
- As the substance showed corrosive properties the animal was killed for ethical reasons two days after application. The study was considered complete.
- Interpretation of results:
- Category 1B (corrosive) based on GHS criteria
- Remarks:
- Migrated information
- Conclusions:
- Because a 3-min exposure resulted in necrotic effects 1 and 2 days after application, but not at 1 h after application, the test material is considered corrosive to rabbit skin, and should be classified in Category 1B according to OECD-GHS.
- Executive summary:
At the request of CECA S.A., Paris-la-Defense, France, the potential of the test substance DINORAMOX S3 (batch No. 96102808) to induce skin irritation was evaluated in rabbits according to OECD (No. 404, 17th July 1992) and EC (92169lEEC. B.4, 31st July 1992) guidelines. The study was conducted in compliance with the principles of Good Laboratory Practice Regulations. The study design was established according to available information on the test substance and the above guidelines. The test substance was applied in a first assay for a period of 3 minutes and 4 hours to one male New Zealand White rabbit. A single dose of 0.5 ml of the undiluted test substance was applied to the closely-clipped skin of one flank. The test substance was held in contact with the skin by means of a semi-occlusive dressing. Cutaneous reactions were observed approximately 1 hour, 24 and 48 hours after removal of the dressing. As the test substance showed corrosive properties in this first assay, the animal was killed for ethical reasons 2 days after application. The study was considered complete and the test substance was not evaluated on other animals. After a 3-min exposure: No cutaneous reactions were observed at the 1 -hour reading. A severe erythema and a severe oedema, together with cutaneous necrosis, were noted on days 2 and 3. After a 4 -hour exposure: A well-defined erythema and a slight oedema were observed at the 1-hour reading. A severe erythema and a severe oedema, together with cutaneous necrosis, were noted on days 2 and 3. Under these experimental conditions and according to the classification criteria laid down in OECD-GHS, the test substance DINORAMOX S3 (batch No. 96102808) should be considered as corrosive (Category 1B) when applied topically to rabbit skin.

Additional information
Evaluation of dermal irritation/corrosion of Tris (2-hydroxyethyl) oleyl diaminopropane (recently redefined as Amines, N-(C18 unsaturated, alkyl) trimethylenedi-, ethoxylated (NLP), CAS 1268344-02-0), also referred to here as Oleyl-diamine3EO:
In order to limit animal testing with corrosive material, use is made ofread-across from the tallow-diamine3EO to Oleyl-diamine-3EO. This read-across is acceptable as these chemicals share the same structure and properties. The difference is a slightly lower alkyl chain for the tallow and a higher level of unsaturation of the oleyl. (See also separate document in support to read-across).
There is only one study available of high quality, in which Tallow-diamine3EO has been evaluated for acute dermal irritation/corrosion in rabbits according to OECD 404 and in compliance to GLP.
The test substance was applied in a first assay for a period of 3 minutes and 4 hours to one male New Zealand White rabbit. A single dose of 0.5 ml of the undiluted test substance was applied to the closely-clipped skin of one flank. The test substance was held in contact with the skin by means of a semi-occlusive dressing. Cutaneous reactions were observed approximately 1 hour, 24 and 48 hours after removal of the dressing. As the test substance showed corrosive properties in this first assay, the animal was killed for ethical reasons 2 days after application.
Results after a 3-min exposure: No cutaneous reactions were observed at the 1-hour reading. A severe erythema and a severe oedema, together with cutaneous necrosis, were noted on days 2 and 3. After a 4 -hour exposure: A well-defined erythema and a slight oedema were observed at the 1-hour reading. A severe erythema and a severe oedema, together with cutaneous necrosis, were noted on days 2 and 3. Based on the results of this study, Tallow-diamine3EO is considered to be severe corrosive to the skin.
Testing with Oleyl-diamine3EO can be expected to lead to similar results, and in order to limit unnecessary animal testing with corrosive substances, no further studies are considered.
Eye irritation:
Due to corrosive properties in de dermal irritation/corrosion studies with this substance testing in eyes would not be required.
Justification for classification or non-classification
Available data indicate corrosive properties following exposures of 3 minutes and longer. Following exposure of 3 minutes, the skin destruction is observed at examination the next day, but not yet at the observation 1 hour after the exposure. Consequently, GHS classification Corrosive Category 1B is appropriate, with hazard statement H314: Causes severe skin burns and eye damage.
Due to corrosive properties demonstrated in the dermal irritation/corrosion study with this substance, testing in eyes is not justified. Under GHS with the hazard phrase ‘H314 Causes severe skin burns and eye damage’ additional classification for eyes is not necessary.
There is no information is available following exposure via inhalation. However, with a vapour pressure below 0.0015 Pa at 20°C, the potential for inhalation of vapours is limited.Also the use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalation route will be unlikely to occur.Consequently, despite the irritant nature of the substance, respiratory irritation is not expected, and classification STOT-SE Cat.3 for respiratory irritation is not required.
